Plot the point (3, 2pi/3), given in polar coordinates, and find other polar coordinates (r, θ )of the point for which the foll

exis [7]

Answer:

(a) $(3, -\frac{4\pi}{3})$

(b) $(-3, \frac{5\pi}{3})$

Step-by-step explanation:

All polar coordinates of point (r, θ ) are

$(r,\theta+2n\pi)$ and $(-r,\theta+(2n+1)\pi)$

where, θ is in radian and n is an integer.

The given point is $(3, \frac{2\pi}{3})$ . So, all polar coordinates of point are

$(3, \frac{2\pi}{3}+2n\pi)$ and $(-3, \frac{2\pi}{3}+(2n+1)\pi)$

(a) $r>0,-2\pi\leq \theta$

Substitute n=-1 in $(3, \frac{2\pi}{3}+2n\pi)$ , to find the point for which $r>0,-2\pi\leq \theta$ .

$(3, \frac{2\pi}{3}+2(-1)\pi)$

$(3, -\frac{4\pi}{3})$

Therefore, the required point is $(3, -\frac{4\pi}{3})$ .

(b) $r$

Substitute n=0 in $(-3, \frac{2\pi}{3}+(2n+1)\pi)$ , to find the point for which $r>0,-2\pi\leq \theta$ .

$(-3, \frac{2\pi}{3}+(2(0)+1)\pi)$

$(-3, \frac{2\pi}{3}+\pi)$

$(-3, \frac{5\pi}{3})$

Therefore, the required point is $(-3, \frac{5\pi}{3})$ .

Substitute n=1 in $(3, \frac{2\pi}{3}+2n\pi)$ , to find the point for which $r>0,2\pi \leq \theta$ .

$(3, \frac{2\pi}{3}+2(1)\pi)$

$(3, \frac{2\pi}{3}+2\pi)$

$(3, \frac{8\pi}{3})$

Therefore, the required point is $(3, \frac{8\pi}{3})$ .

answer=288

you add 256 into 32 to get 288 so then you get 288

You need 660 mL of a 40% alcohol solution. On hand, you have 35% alcohol mixture. You also have a 95% alcohol mixture. How much

ozzi

Answer:

A. 605 mL of the 35% solution

B. 55 mL of the 95% solution

Step-by-step explanation:

It is given that, you need 660 mL of a 40% alcohol solution. On hand, you have 35% alcohol mixture. You also have a 95% alcohol mixture.

Let x and y be the amount of 35% alcohol solution and 95% alcohol solution (in mL) respectively.

So,

Amount equation: $x+y=660$ ...(1)

Alcohol equation : $0.35x+0.95y=0.40(660)\Rightarrow 0.35x+0.95y=264$ ...(2)

On solving (1) and (2), we get

$0.35(660-y)+0.95y=264$

$231-0.35y+0.95y=264$

$0.6y=264-231$

$y=\dfrac{33}{0.6}$

$y=55$

Now, substitute y=55 in (1).

$x+55=660$

$x=660-55$

$x=605$

Therefore, we need 605 mL of the 35% solution and 55 mL of the 95% solution.
